So I snapped my gas inlet port off the solenoid and Everlast had a replacement delivered in like 3 days on their dime; freaking amazing! I understand the fitting doesn't hold up to too much torque(guess how I snapped my previous one..) and I'd like to use some sort of thread sealant. Loctite has pretty much anything you can imagine but I want to know what works best, or what Everlast used in the initial assembly.

I'm leaning towards Loctite 577, but wanted to see if there was something recommended.
